Finding and filming Tiger Snakes around Melbourne is "my thing" and I've seen and filmed them catching frogs countless times. Normally the strike happens under leaf litter or a fallen branch and there isn't really much to see. But occasionally the frog makes a break for it and tries to jump to safety; and if the snake realises what's happened quickly enough, well, that's when things get really exciting:
